摘要： A method for the handling of melt samples in a steelworks laboratory may involve processing and/or analyzing a melt sample in at least one first treatment apparatus and subsequently transporting the melt sample via at least one first transport path to at least one second treatment apparatus where the melt sample is subjected to further processing and/or analysis. As part of the transporting step, the method may involve clamping the melt sample on a sample carrier so that the sample carrier is transported together with the clamped-in melt sample between the treatment apparatuses and is positioned in the treatment apparatuses for processing and/or analysis.

摘要： A casting solidification analysis method, which can analyze positions of shrinkage cavities more accurately than in the past, a casting method using the above method, and an electronic program are provided. A following casting solidification analysis method is provided. An amount of expansion/shrinkage for each solidification step length separated by inflection points in a cooling curve is determined, by setting a solid phase ratio at a completion of pouring to 0, setting a solid phase ratio at an end of solidification to 1.0, and determining the expansion/shrinkage amount for the each solidification step length by proportionally distributing the each solidification step length to the total solid phase ratio length.
